Description

Technical Field

[0001] This utility model relates to the field of giant panda mouth opening technology, and more specifically, to an adjustable giant panda anesthesia mouth opening device. Background Technology

[0002] In the medical care and research of giant pandas, when a giant panda is under anesthesia, it is often necessary to open its mouth to perform critical procedures such as tracheal intubation and oral examinations. Maintaining the mouth in a stable open state throughout the anesthesia process places extremely high demands on the suitability and safety of the mouth-opening tools. Suitable mouth-opening tools must not only reliably support the mouth to prevent obstruction or injury due to the animal's involuntary closure, but also adapt to the differences in oral size among giant pandas of different ages and sizes, as well as the varying degrees of opening required at different stages of the same procedure.

[0003] Currently, the simple mouth-opening device used for anesthetizing giant pandas mainly relies on different models of support columns to adapt to different individuals. The procedure involves determining the size of the panda's mouth on-site and then selecting the corresponding model of support column for installation and fixation. However, this method has significant limitations: on the one hand, it requires stocking multiple models of support columns to address individual differences, increasing instrument management costs and preparation time; on the other hand, during the same procedure, such as tracheal intubation requiring a larger opening while maintaining anesthesia only requires a smaller opening, the support column must be changed to meet the needs. This is not only cumbersome and inefficient, but also may cause unnecessary stimulation to the anesthetized panda due to frequent instrument changes, and may even pose a risk of damaging oral tissues or teeth, making it difficult to balance operational flexibility with animal comfort. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable mouth opener for anesthetizing giant pandas, which solves the problem that existing mouth openers cannot flexibly adjust the degree of opening.

[0005] This utility model is achieved through the following technical solution: an adjustable mouth opener for anesthetizing giant pandas, including an adjustable support frame, the adjustable support frame being a movable quadrilateral structure, a set of vertically arranged diagonal plates of the adjustable support frame with bite pads that contact the giant panda's teeth respectively hinged, and a set of horizontally arranged diagonal plates of the adjustable support frame with adjusting rings respectively hinged, and bolts passing through the adjusting rings in sequence and nuts connected to the bolt threads are used to adjust the distance between the bite pads.

[0006] Furthermore, the bite pad has grooves that mate with the giant panda's canine teeth.

[0007] Furthermore, the threaded end of the bolt is provided with a connecting hole, which is used to connect the anti-detachment rope to prevent the adjustment support frame from slipping into the giant panda's mouth.

[0008] Furthermore, the bite pad has a trapezoidal structure, and the large bottom surface of the bite pad is in contact with the giant panda's teeth.

[0009] Furthermore, adjustable support frames are arranged on both sides of the giant panda's mouth.

[0010] Furthermore, adjust the four sides of the support frame to be of equal length.

[0011] Furthermore, the bite pad is made of silicone.

[0012] Furthermore, the adjustment support frame is made of stainless steel.

[0013] This utility model has at least the following advantages and beneficial effects: by adjusting the support frame with a movable quadrilateral structure and by using bolts and nuts to adjust the horizontal diagonal, the distance of the bite pads on the vertical diagonal can be changed. It can adapt to the oral cavity size of giant pandas of different sizes without replacing parts, solving the cumbersome problem of frequent replacement of support columns in the prior art, and improving the operational flexibility and applicability.

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example

[0021] like Figures 1 to 4As shown in this embodiment, an adjustable mouth opener for giant panda anesthesia is disclosed, used to open and maintain the oral cavity of giant pandas under anesthesia, and adapted for procedures such as endotracheal intubation and oral examination. Its main structure includes an adjustable support frame 1, which is a movable quadrilateral structure. A set of diagonally arranged vertical sections of the adjustable support frame 1 are hinged to occlusal pads 2 that contact the giant panda's teeth. A set of diagonally arranged horizontal sections of the adjustable support frame 1 are hinged to adjusting rings 3. Bolts 4 pass through the adjusting rings 3 sequentially, and nuts 5, threadedly connected to the bolts 4, are used to adjust the distance between the occlusal pads 2. Specifically, the threaded sections of the adjusting rings 3 and bolts 4 are clearance-fitted, and hinged ear plates are provided at both ends of the adjusting rings 3; the occlusal pads 2 are also hinged to the adjustable support frame 1 via these ear plates. During operation, one hexagonal end of bolt 4 extends into the giant panda's mouth. Once in the appropriate position, one hand holds the part of bolt 4 protruding from the mouth, while the other hand tightens nut 5. This causes nut 5 and the end of bolt 4 to abut against adjusting ring 3, bringing the horizontally arranged set of adjusting rings 3 closer together. Due to the deformation characteristics of the quadrilateral structure, the vertical spacing of the occlusal pads 2 is increased. Utilizing the mobility of the quadrilateral structure, combined with the adjustment of the horizontal diagonal using bolt 4 and nut 5, the distance of the occlusal pads 2 on the vertical diagonal can be changed in real time. This allows for adaptation to the oral cavity sizes of giant pandas of different sizes without replacing any parts, as well as addressing the differentiated needs of "larger opening during intubation and smaller opening during maintenance anesthesia" in the same operation. This solves the cumbersome problem of frequent support column replacements required by existing technologies, improving operational flexibility and applicability.

[0022] Furthermore, in a specific implementation, the occlusal pad 2 provided in this embodiment of the invention has a dental groove 20 that mates with the canine teeth of a giant panda. Specifically, the dental groove 20 is conical, complementing the shape of the canine teeth, which enhances the fit between the occlusal pad 2 and the teeth, preventing the mouth opener from slipping due to slight shaking or force on the animal during use. This ensures stable oral opening and reduces relative friction between the teeth and the occlusal pad 2, lowering the risk of tooth damage. It is especially suitable for scenarios where the animal cannot cooperate voluntarily under anesthesia.

[0023] Furthermore, in a specific implementation, a connecting hole 40 is provided at the threaded end of the bolt 4 provided in this embodiment of the invention. The connecting hole 40 is used to connect an anti-slip rope to prevent the adjusting support frame 1 from slipping into the giant panda's mouth. Giant pandas under anesthesia cannot control their oral cavity movements independently. This structure can fix the mouth opener to the outside through the anti-slip rope, preventing the mouth opener from slipping out of the mouth due to accidental loosening, thus preventing it from falling into the throat and causing suffocation or tissue damage, significantly improving safety in use.

[0024] Furthermore, in a specific implementation, the bite pad 2 provided in this embodiment of the present invention has a trapezoidal platform structure, and the large base of the bite pad 2 contacts the panda's teeth. The larger contact area between the large base of the trapezoidal platform and the teeth can distribute the pressure on the teeth and avoid excessive local force leading to tooth damage; at the same time, the larger base has stronger conformity, which can further enhance the stability of the bite pad 2 and the teeth and reduce discomfort during long-term use.

[0025] Furthermore, in specific implementation, the aforementioned adjustable support frame 1 provided in this embodiment of the utility model is respectively arranged on both sides of the giant panda's mouth. This allows the occlusal pad 2 to be positioned on the upper and lower canines on both sides of the giant panda's mouth, ensuring balanced force on both sides of the mouth and avoiding mouth tilting or local tissue compression caused by unilateral support, thus ensuring a stable mouth opening. At the same time, conforming to the physiological structure on both sides of the mouth reduces pressure on the soft tissues inside the mouth, improving the giant panda's comfort under anesthesia.

[0026] Furthermore, in specific implementations, the four sides of the adjustment support frame 1 provided in this utility model embodiment are of equal length. The adjustment support frame 1 forms a rhombus or square structure, and during the adjustment process of the bolts 4 and nuts 5, the extension and contraction amplitudes of the two sides are symmetrical, the force is more even, and it can avoid adjustment jamming or local stress concentration caused by unequal side lengths, ensuring smooth and stable opening and closing process and extending the service life of the adjustment support frame 1.

[0027] Furthermore, in specific implementation, the occlusal pad 2 provided in this utility model embodiment is made of silicone material, which has good elasticity and softness. When in contact with teeth and gums, it can buffer pressure and avoid scratching of tooth enamel or gum tissue by hard materials (such as metal). At the same time, the surface friction of silicone is moderate, which can enhance the fit with teeth, reduce slippage, and is resistant to disinfection (can withstand high temperature or chemical disinfection), making it suitable for repeated use in medical scenarios.

[0028] Furthermore, in specific implementation, the aforementioned adjustable support frame 1 provided in this utility model embodiment is made of stainless steel, which has high strength and rigidity, can stably support the biting force when the giant panda's mouth is closed, and ensure that the open state does not fail; at the same time, it has excellent corrosion resistance, can withstand frequent cleaning and disinfection (such as high-pressure steam sterilization), meets the hygiene requirements of medical devices, and has a long service life, which can adapt to the long-term repeated use scenario in giant panda protection research.
